We use the same proven technology from Instant Heart Rate to detect your heart pulse and objectively measure the effects of stress on your body. Describe your mood by selecting energy and positivity level. Select stressors to combine your subjective emotional stress into the overall result.

Everyone has experienced changes in heart rate before taking an exam, giving a public speech, or when exercising. Not only does your heart rate increase, but the intervals between consecutive heartbeats changes as well. By Poincare plot analysis of your pulse data, using your iPhone's built-in camera, we can estimate your level of physiological stress in less than a minute!

Stress Check 2 utilizes Azumio patented algorithm, based on Poincare plot analysis of your heart pulse, to determine physiological stress. Overall Stress level is derived by combining physiological stress data with emotional self-assessment of stress. Our algorithms follow recommendations of the European Society of Cardiology (ESC) and the North American Society of Pacing and Electrophysiology (NASPE).
